Compare energy prices

Most of the UK’s energy suppliers are signed up to the Energy Switch Guarantee, which guarantees that the supplier you’re switching to will complete the process, and that it will be done within five days.

There’s also a two-week ‘cooling off’ period, during which you can cancel the switch free of charge.

There’s no need to get in touch with your old supplier once you’ve made your energy switch. Once they’ve received notification of your switch, the supplier should send a final bill and close your old account once you’ve paid any outstanding amount. While there’s no need to cancel your Direct Debit, you can do this through your bank if you want to be more confident you won’t still be charged – just remember to settle your final bill first.

Your gas and electricity won’t be interrupted at any time - even if your supplier goes out of business and you’re transferred to another supplier, the lights and heating will stay on. In the case of switching, most energy suppliers are signed up to the Energy Switch Guarantee, which requires switching for customers to be reliable and hassle-free. With that in mind, any problems involving the interruption of your supply are extremely unlikely.

You can switch energy supplier if you’ve been in debt for fewer than 28 days - the money you owe will be added to your final bill. If you’ve been in debt for longer, you probably won’t be able to switch until you’ve settled that debt (unless the supplier’s billed you incorrectly). 

If you’re on a prepayment meter, you can switch as long as the debt to your current supplier isn’t greater than £500.

If you’re moving and you want to take your current deal with you, let your provider know - depending on where you’re moving to, you may be able to take it with you. Otherwise, you’re free to switch away from the supplier in residence at your new property in the normal way.

One thing to remember to do is take a meter reading on the day you move out, and take another one at the new property - this will ensure you’re only paying for what you use. Read more in our guide.

You can compare energy prices by providing your postcode and usage details (starting with the postcode entry box at the top of this page) so we can show you the deals available in your area along with the estimated savings based on your current usage.

In order to switch energy supplier, you’ll need:

• Your address

• Your tariff name.

Uswitch will collect your usage data and current supplier from your address details.

You don’t necessarily need all that to compare energy deals, but you run the risk of an inaccurate personal projection and savings estimate if you don’t provide as much information as possible at the start of the process. 

You can usually switch energy supplier if you’re a renter as long as you pay the energy bills. If the landlord pays the energy bills, you will need to get their permission.

If you want to only see gas deals or electricity deals, you can filter available tariffs on our results table.

When you confirm your switch, you’ll get a confirmation email from your chosen supplier within a day or two to let you know that it’s going ahead. Once it’s completed, which should be within 14 days, you’ll get another onboarding email letting you know that you’re officially getting your energy from your new supplier. Your supply won’t be cut off at any point, so you can sit back and relax.

If you don’t want to switch energy supplier, you still might be able to find a cheap gas and electricity deal with Uswitch. If you haven’t switched energy before it’s likely that you’re on your provider’s standard variable or default tariff, which is typically the most expensive type of plan on offer. You can use Uswitch to compare energy deals from your current provider if you’re happy with the service but want to save on your energy bills.
